2.19.6: Checkerboard (python) Write a program that will draw a red and black checkerboard on the canvas. Squares should have side lengths of 40 pixels. They should alternate between black and red and each row should start with a different color. Hints: - You should use a variable called color_value to control the color of each square. - The Bubble Wrap program might be a good place to start. You can find it here!

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
